HASP LOCK.

Application filed. Gctober 27, 1929.

T 0 all 107mm it may concern Be it known that 1, EMMA KNAPP, a citizenof the United States, residing at Denver, in the county of Denver andState of Colorado, have invented certain new and useful imp:)VGlllGll'tS in s) Locks, of which the following is a specification.

This invention relates to impro ements in hasp-locks and its primaryobject is to provide in association with the staple of a fastening ofthis character an adjustably mounted lock adapted to secure the hasp inits operative position thereon.

In the accompanying drawings in the vari ous views of which like partsare similarly designated,

Figure 1 represents an elevation of the cooperating members of myimproved hasp lock in its open condition;

Figure 2, a similar View showing the parts in their closed position;

Figure 3, a plan view of a modified construction of the fastening;

Figure i, a side elevation of the same in the unlocked condition, and

Figure 5, a view similar to that of Figure L showing the parts of themodified form of my invention in their locking position.

Referring first to Figures 1 and 2 of the drawings, the referencecharacters :2 and 3 designate two related objects such as a door and itscasing or a box and its lid, to which my improved hasp-lock is applied.

The hasp-lock consists of a staple 4 fastened on a base 5 by means ofwhich it is secured to one of the objects, and a hasp 6 which is hingedto a plate 7 secured to the other object, in cooperating relation to thestaple.

The staple base 5 has an extension 5 for the movable support of the lock8 which may be of any suitable construction to cooperate with the staplefor the purpose of securing the hasp in place thereon.

The lock in the construction shown in the drawings consists of a housingcontaining the usual key-actuated mechanism for the projection andretraction of a shackle which in practice passes through the staple.

The means for mounting the lock on its support comprises a pair ofparallel links 9 which at their ends are pivotally connected tocorrespondingly position knuckles formed respectively on the supportandat the under side of the lock.

Serial No. 419,787.

The end of the look at which its shackle is located faces the staplewhen the fastening is in its unlocked condition as shown in Figure 1 ofthe drawings, and it will be apparent that by very simple manipulationthe lock may be instantly adjusted to its operative position withrelation to the staple as illustrated in Figure 2.

The modification of my invention shown in Figures 3 to 5 is, owing toits compactness of construction, particularly adapted for use onflexible objects s ch as the straps used for closing mail sacks and thelike.

The lock support, 5 is in this form of the invention formed at an angleto the base plate of the staple, which is fastened at an end portion ofthe strap 10 to cooperate with the hasp connected at the opposite end ofthe same through the medium of a link 12.

The links and 141 by which the iock is mounted on the support are ofdissimilar lengths and they are pivotally connected to knuckles at theunder side of the lock as in the first-described construction and tocorresponding knuckles at the opposite ends of the support.

A spring 15 fastened to one of the links limits the movement of the lookaway from the staple and a lever 16 fulcrumed on the pivot by which theother link is connected to the knuckle of the support, serves in theoperation of the device to lift the hasp while the lock is beingseparated from the staple whereby to facilitate its removal.

One of the arms of the lever, to this end contacts with the under sideof the moving look as shown in Figure a, while its opposite arm engagesthe under side of the hasp.

it will be seen that while in the construction shown in Figures 1 and 2the lock moves linearly toward and from the staple, it is in the otherform of the invention moved in an arc owing to the difference in lengthof the two links by which it is mounted on its support.

Having thus described my invention what I claim and desire to secure byLettersPatent is:

1. A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith. a lock-support, and a lock having a link-connection with saidsupport for its adjustment to and from the staple.

2. A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith, a

lock-support, and a lock having a double link-connection with saidsupport for its adjustment to and from the staple.

3. A hasp-lock comprising in combination, a staple having abase-plate, ahasp cooperating with the staple, a lock support formed on thebase-plate, and a lock having a linkconnection with said's'upport forits adjustment to and from the staple.

4. A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith, a lock-support, a lock adapted to operatively engage thestaple, and two linkspivoted to the support and to the lock foradjustment of the latter to and from the staple. 5. A hasp-lockcomprising in combination, a staple, a hasp cooperating therewith, alock-support, a lock adapted to operatively engage the staple, and twolinks of unequal lengths pivoted to the support and-to the lock foradjustment of the latter to and from the staple.

6. A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith, a lock-support, a look adapted to operatively engage thestaple, and two parallel links pivoted to the support and to the lockfor ad justment of the latter to and from the staple.

7 A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith, a lock-support, a lock having a link-connection with saidsupport for its adjustment to and from the staple, and a lever engagedby the lock to be moved about its fulcrum during movement of the lockaway from the staple and having a lifting action on the hasp in itsoperative position on the staple.

8. A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith, a lock-support, a lock having a link-connection with saidsupport for its adjustment to and from the staple, and a lever fulcrumedon the support, and having an arm in the path of the lock and anotherarm. extending alongside of the staple to lift the hasp.

9. A hasp-lock comprising in combination, a staple, a hasp cooperatingtherewith, a lock support, a lock adapted to operatively engage thestaple, two links pivoted to the support and to the lock for adjustmentof the latter to and from the staple, and a lever fulcrumed to moveabout a pivotal axis of one of the links and having an arm in the pathof the lock and another arm extending alongside of the staple to liftthe hasp.

10. A hasp-lock comprising in combination,a staple, a hasp cooperatingtherewith, a lock-support, a lock having a link-connection with saidsupport for its adjustment to and from the staple, and means forlimiting the movement of the look away from the staple.

In testimony whereof I have affixed my signature.
